I built a 347 for my 91 LX that ran great for a couple months and yesterday something went wrong. I got on it and it stuttered and power was no longer at about 5500 so i back off. And now it feels like its got a huge vibration at any RPM but Idles fine. What does a Blown head gasket feel like? could it be something internal?
Thanks, Mark

CHECK the balancer also since you have some vibration.

sounds like you lost a cylinder.
